The 30-year-old pop superstar, who has become more open about her personal life since becoming a mother to daughter Blue Ivy in January, has posted a picture of her in the micro-blogging site Twitter, reported Daily Star.
In the picture, the 'Crazy In Love' hitmaker is shown without make-up as she gazes seductively into the camera, seemingly wearing nothing but Jay-Z's diamond and platinum necklace.
She holds it between her lips as her curly brown hair falls on her breast to preserve her dignity.
"Got the hottest chick in the game wearing my chain," Jay Z tweeted.
